Background-This prospective, randomized, controlled clinical trial compared changes in exercise performance and daily ambulatory activity in peripheral artery disease patients with intermittent claudication after a home-based exercise program, a supervised exercise program, and usual-care control. Methods and Results-Of the 119 patients randomized, 29 completed home-based exercise, 33 completed supervised exercise, and 30 completed usual-care control. Both exercise programs consisted of intermittent walking to nearly maximal claudication pain for 12 weeks. Patients wore a step activity monitor during each exercise session. Primary outcome measures included claudication onset time and peak walking time obtained from a treadmill exercise test; secondary outcome measures included daily ambulatory cadences measured during a 7-day monitoring period. Adherence to home-based and supervised exercise was similar (P=0.712) and exceeded 80%. Both exercise programs increased claudication onset time (P<0.001) and peak walking time (P<0.01), whereas only home-based exercise increased daily average cadence (P<0.01). No changes were seen in the control group (P>0.05). The changes in claudication onset time and peak walking time were similar between the 2 exercise groups (P>0.05), whereas the change in daily average cadence was greater with home-based exercise (P<0.05). Conclusions-A home-based exercise program, quantified with a step activity monitor, has high adherence and is efficacious in improving claudication measures similar to a standard supervised exercise program. Furthermore, home-based exercise appears more efficacious in increasing daily ambulatory activity in the community setting than supervised exercise.
